Application filed August 22 1892. Renewed June 17, 1893. Serial No.478,007. (No model-l 170 a whom it may concern.-

Be it known that I, EDWARD A. QUIsEN- BERRY, of Lexington, in the countyof Rockbridge and State of Virginia, have invented certain new anduseful Improvements in Car- Heaters; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawing,and to the letters of reference marked thereon, which form part of thisspecification.

This invention relates to certain improvements in car heaters.

The object of the inventionis to provide an improved arrangement wherebythe heat in or amount of heat supplied to each car can be readily andeasily regulated by a very simple and easily understood means andarrangement.

The invention consists in certain novel features of construction and incombination of parts more fully described hereinafter and particularlypointed out in the claims.

The accompanying drawing showsin diagram, the arrangement of pipes andregulat ing valves.

In the drawing the reference letter a, indicates a locomotive boiler.

1), indicates the water tank of the tender.

0, indicates the cars.

d, indicates a supply conduit or pipe extending from the locomotiveboiler preferably at a point below the water line thereof, rearwardly sothat its rear end at the end of the tender can be detachably connectedby suitable couplings with the train pipes.

The outgoing or supply train pipes e, are doubled or looped throughoutthe length of each car, each pipe forming a continuous loop. The ends ofeach loop extend transversely of the ends of the car and are providedwith the projecting ends f, having flexible ends and coupling members 9,so that the various supply pipes of the cars are connected to form acontinuous conduit throughout the train. Each projecting end is providedwith a cut 0E valve h, for obvious reasons.

The return heating pipes z, are formed in a corresponding manner to thesupply pipes in the form of continuous loops having their ends extendingtransverse of the car ends. These return pipes are provided with theheating coils j, suitably arranged within the cars. The return pipeendsare usually located in the same vertical planes as but above thesupply pipe ends and are provided with the outwardly extending ends7a,.having flexible sections and coupling means Z, so that all thereturn pipes of the various cars can be coupled together to form thereturn conduitof the train. These ends lo, are also provided with thecut off valves m, so that the ends can be closed when the couplings arebroken. Vertical pipes n connect the corresponding ends in each car ofthe looped supply and return pipes, and each vertical cross pipe isprovided with a cut off valve 0. In operation the valves in all of theseconnecting pipes n, are closed except the one at the rear end of thelast car of the train which is open so that the heating medium can flowthroughout the length of the supply conduit and then up through said endconnecting pipe into the heating and return conduit. By the arrangementdisclosed any car can be the rear car of the train and it makes nodifference which end of the car forms its front end. The return conduitconnects with the pipes, on the tender extending down into the watertank thereof with its discharge end near the bottom or at least belowthe water line of the tender. This pipe g, on the tender is providedwith a spring valve r, yieldingly tending to prevent the outflow ofwater from the train pipes into the tender tank, and thereby maintaininga pressure in the train pipes and preventing a too rapid flow of thewater therethrough under low pressure.

One side of the supply pipe in every car is permanently open that ispreferably has no valves, while the opposite side of each looped supplypipe is provided with two valves 8, 8, near its ends and usually in thecar so that they can be easily operated from the interior of the car.The return heating pipes are provided with valves t, t, after the sameplan. One side of each looped return pipe (preferably the side next tothe open side of the supply pipe) is provided with the two valves t, t,near its opposite ends so that that side of the loop within the car canbe entirely shut ofi, while the other side of the loop is entirely openand without closing. valves. By means of this-arrangement the heat ineach car can be nicely regulated. By closing the valves 8, s, in a carone side of the supply pipe is cut off from the heating supply and theradiating surface is correspondingly reduced in the ear, the

heat supply to the remainder ofthe trainflowing through the other sideof said pipe. If it is desired to still further reduce the radiatingsurface in the car the valves 15, t, can be closed thereby shutting outone side of the heating return pipe. The radiatingsurface is thusreduced one half, and can be easily and quickly regulated.

The system here illustrated is particularly to heat the cars byradiation from hot water forced through the train pipes by the pressurein the boiler. The water after passing through the train pipes isdischarged into the tender tank. this means be independently regulated.The pipes in one car can be shutoff as completely as possible while thepipes in the next car to the rear or to the front can be openedcompletely.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. A car heating system comprising the supply conduit having the singleconnnections between the cars and looped in the cars so that the twosides of the conduit extend longitudinally of the car and at their endsconnected with said single connections, one side The heat in each carcan byof said conduit being permanently open through the car, a cut offvalve in the other side of said conduit, the return conduit having thesingle connections between the cars and looped in the cars so that thetwo sides of .theconduit extend longitudinally of the car and at theirendsconnect with said single connections, one side of said conduit beingpermanently open, and a cut off valve in the other side of said returnconduit as and for the purposes set forth.

2. A car heating system the supply conduit having the single valvedconnections between the cars, and looped in the cars, the sides of eachloop extending longitudinally of and on opposite sides of the-car, oneside of the loop having a cut oif valve, the return pipe havingthesinglcva-lved connections between the cars and looped in the cars,'thesides ofleach loop extending longitudinally of and on opposite. sides ofthe. ear, and a cut oif valve in the side of each return loop on theopposite side of the car from. the side of the supply loop having a cutoif valve, as-set forth, the supply and return loops in each carconnected at their ends by valved connections, substantially asdescribed.

In testimony that I claim the foregoing as my 'own I affix my signaturein presence of two witnesses.
